Question

State whether true or false:
Eutrophication leads to a steep increase in BOD and causes a hypoxic condition in water bodies.

• A. True
• B. False

Answer 1

The correct option is A True

Eutrophication leads to algal bloom. Once the algae die, the organic matter left behind starts to get decomposed by bacteria. These bacteria consume large amounts of oxygen. This increases the biological oxygen demand or BOD, and causes a hypoxic condition in the water body, which is not ideal for aquatic life forms.
